A series of amidocyclopropanes were prepared by directamidocyclopropanation of alkenes, usingorganozinccarbenoids generated from readily available diethoxymethylamides. The amidocyclopropanation of monosubstituted alkenes led to selective formation of the trans-amidocyclopropane in most cases, but with more substituted alkenes, the stereochemical outcome of the cyclopropanation reactions was unpredictable

The use of sulfate additives such as H(2)SO(4) greatly increases the reactivity of palladium catalysts for the cyanation of aryl and heteroaryl chlorides and renders them more robust toward adventitious air. Using this method, a wide variety of aromatic and heteroaromatic nitriles were prepared in high yield. (C) 2010 Elsevier Ltd. All rights reserved.
